Macro Lens and Flip Up Cap for HTI-19/HTi-18 Thermal Imaging Camera

thingiverse

This macro lens adapter / flip up lens cover makes it possible for a HTI-19 or HTI-18 thermal imaging camera to focus at just 2 inches away. The macro lens folds up and out of the way, like the standard lens cover, allowing normal long distance viewing to take place. Close examination of PC board components is also feasible with this macro lens. Dedicated to Diana Adamic, Tia, and Steve Salika They were some of the kindest, most wonderful people we had the privilege to be close friends with for a long time. It was one of Steve's humorous little stories that got me looking into thermal cameras in the first place. This project wouldn't exist without him. Sadly, Steve, Diana, and their daughter Tia were lost in a boat fire while they were celebrating Tia's 17th birthday. They were doing something they all loved at the time. The rabbits will miss them very much. --- Comments: This flip up lens cover and macro lens adapter replaces the standard lens cover of the HTI thermal imaging camera. This macro lens adapter then flips open/closed just like the original cover, but when in closed position puts macro lens in front of camera. A 20.0 mm diameter, 50.8 FL ZnSe lens fits perfectly in this holder and allows focusing down to 2 inches away from the subject. Individual board components and pins can be easily imaged with this setup. Remove existing lens cover by cutting through one of its hinge pins with a hobby knife. This lens cover then snaps into the vacant mount securely. The ZnSe lens is held firmly in place using a round plastic retaining ring. Tack weld the ring in place with a soldering iron to secure the lens properly. - changes 2019-10-06 The holder and snap were slightly tightened to help hold position better. Intrinsic supports were added for easier printing.
